If there's one over-used buzzword currently making the rounds in the technology industry, it's 'post-PC world' - or the notion that desktops and laptops are a dying breed. Todd Bradley, executive vice president of HP's printing and personal systems group, thinks this is a nonsensical notion - and he's right.

Tablets have emerged offering a hybrid and are cutting deeply into PC sales. There cannot be a debate about if, what was claimed has already happened.

Just one slight problem with your comment... It's not true. PC sales remain consistent and have seen very little impact due to tablets. People are not replacing PC purchases with tablet purchases. The theory that PC sales are being "deeply cut into" by anything is simply not supported by any facts.

So we are talking (2012 isn't over) something like 30-60m less PCs sold this year than would have happened without the tablet based fall off.

You're confusing people not upgrading their PCs as often due to no need (which has happening before tablets hit the scene), with people replacing PCs with tablets -- which they are not. As much as you want to believe tablets are smashing PC sales, the facts just don't support it. When cherry-picking a bit here or there is the only way to give the impression that your claim is supported, there's something wrong with your claim.
